AMD has published a test version of the ATI Stream Encoder Plugin for Adobe Premier Pro CS4, you can download it over here. The plug-in is a result of collaboration between AMD and Adobe, all in the goal of utilizing Stream technology to level the load between the CPU and the GPU.

AMD's plug-in will accelerate all ATI Stream capable cards, e.g. Radeon 2000 series onwards. Seeing both consumer and commercial products accelerating a professional application is really beneficiary for the companies in the video business, given that for the price of single professional card you can usually get three to four regular ones. In case of Quadro CX, you can get around five GeForce GTX 285 graphics cards.
